340 rear main seal leak/gush

I fought a small leak till I put sealer between the main and block. Had pan off 5 times new 408. I just put a dab of black RTV at the seal ends. Seems to work for me, but I have considered off setting the seal ends...
Glad you got it to stop. Was the pan gasket re useable? I've known about off setting of the rear main seal for a long time
